Use only the crimped items that meet the conditions
shown in the ACCEPT column.
REJECT terminals, splices, and spare wire caps can
be avoided through careful use of instructions and by
performing regular tool maintenance as instructed in
this document.
NOTE
i
Locators in Crimping Tools 69692-1 and 69693-1
are locked in the down position. Refer to Instruction
Sheet 408-7424 for crimp height inspection of
these tools.
7. MAINTENANCE AND INSPECTION
TE recommends that a maintenance/inspection
program be performed periodically to ensure
dependable and uniform terminations. Tools should be
inspected at least once a month. Frequency of
inspection may be adjusted to suit your requirements
through experience. Frequency of inspection is
dependent upon:
1. The care, amount of use, and handling of the tool.
2. The type and size of the products crimped.
3. The degree of operator skill.
4. The presence of abnormal amounts of dust and
dirt.
5. Your own established standards.
All tools are inspected before packaging. Since there
is a possibility of tool damage in shipment, new tools
should be inspected in accordance with Section 7
when received in your plant. Due to the precision
design, it is important that no parts of these tools be
interchanged except those replacement parts listed in
Figure 13.
7.1. Cleaning
The tool should be immersed (handles partially
closed) in degreasing compound to remove
accumulated dirt, grease, and foreign matter.
NOTE
i
Make certain the degreasing compound does not
attack paint or plastic materials.
Remove remaining degreasing compound with a lint
free cloth. When degreasing compounds are not
available, tool may be wiped clean with a lint free
cloth. Relubricate tool, as instructed in Paragraph 7.3
before placing it back in service.
7.2. Visual Inspection
1. Visually inspect the tool for missing parts, then
operate the tool and note the return action of the
spring-loaded handles. If parts are missing or
defective, refer to Figure 13 for customer
replaceable parts.
Flattened
Broken Corner
Chipped
Edge

2. Visually inspect the die closure surfaces for
flattened, broken, pitted, or chipped conditions.
Although dies may gage within permissible limits,
worn or damaged die closure surfaces are
objectionable and can affect the quality of the crimp.
Examples of possible damaged die closure surfaces
are shown in Figure 8.
7.3. Lubrication
Lubricate all pins, pivot points, and bearing surfaces
with SAE 20 motor oil as follows:
•
Tools used in daily production-Lubricate daily
•
Tools used daily (occasional)-Lubricate weekly
•
Tools used weekly-Lubricate monthly
Wipe excess oil from tool, particularly from crimping
area. Oil transferred from the crimping area onto
certain terminations may affect the electrical
characteristics of an application.
7.4. Gaging the Crimping Chamber
Each tool is inspected for proper die closures before
packaging. An inspection should be performed
periodically to check the tool die closures for
excessive wear.
NOTE
i
The following plug gaging information for insulation
crimping chambers is provided for customers
specifically requiring this information. If plug gaging
is not required, inspect the die closures using an
alternate procedure, i.e., performing the "Insulation
Crimp Adjustment" (see Section 5) and "Visual
Inspection" (see Paragraph 7.2).
